基于国产BIMBase平台的结构模型快速创建方法研究

Research on Rapid Structural Model Creation Method Based on Domestic BIMBase Platform

目前,从CAD图纸到BIM模型的转换是工程师的普遍需求,但现有的翻模工具存在模型信息缺失较多、后期修改工作量大的问题。为满足快速建立BIM结构模型的需求,本文提出了一种基于CAD图纸快速建立BIM结构模型的方法。首先,分析了CAD图素与BIM结构模型元素的对应关系;随后,研究了CAD和国产BIM软件的二次开发关键技术与自动翻模的原理;最后,开发出面向结构专业的三维模型重建系统,并将该系统应用于实际项目,验证了该方法的可行性及系统的高效性。

The conversion from CAD drawings to BIM models is a common and urgent need for engineers,yet existing model conversion tools often result in missing information and require extensive modifications in the later stages.To address the need for rapid BIM structural model creation,this paper proposes a method to quickly establish BIM structural models from CAD drawings.First,the correspondence between CAD pixels and BIM structural model components is analyzed.Next,the key technologies for secondary development of CAD and domestic BIM software,along with the principles of automatic model conversion,are studied.Finally,a 3D model reconstruction system tailored to structural engineering is developed and applied to actual projects,demonstrating the feasibility of the method and the efficiency of the system.
